Cobe is pedantic and annoying, so I had to use switch casing

 int choice = 0;

     while (choice != 2)
     {

     cout << "Please select an option\n";
     cout << "1:Encrypt\n";
     cout << "2:About\n";
     cin >> choice;
     switch (choice)
     {
     case 1:
         {
         cout << "Enter a string\n";
         cin.ignore(1, '\n');
         }
     case 2:
         {
         cout << "Lead development - Adil\n";
            cin.ignore(1,'\n');
         cout << "Algorithm design - Adil\n";
            cin.ignore(1, '\n');
         }
